Glare Handling
This field determines what Communication Manager will do when glare occurs. This field
appears when the Direction field is two-way and the outgoing side of the Trunk Type field is
either .../wink or .../delay.
If you enter control or backoff, and ports for the trunk group are not capable of detecting glare,
warnings are generated. The following circuit packs can detect glare: TN767 (all releases),
TN760C (or later releases), and TN464C (or later releases).

Usage
